COSTOM M87 Pro 75% Wireless Mechanical Keyboard — Industrial Gray, Linear Switch, Hot-Swappable, CNC Media Knob & OLED Screen, PBT Keycaps

Compact 75% form factor: the COSTOM M87 Pro packs pro-level controls into a reduced footprint while maintaining a full set of essentials. A vivid color OLED provides instant visual feedback—displaying GIFs, caps lock, connection mode, WIN/MAC indicator and battery status at a glance. Precision media and quick controls: a CNC metal media knob plus multi-function dials let you change volume, connection, backlight brightness/speed, RGB mode/color and language without interrupting your workflow. Flexible connectivity: switch between USB-C wired, Bluetooth 5.1 and 2.4GHz dongle modes for low-latency gaming or multitasking; mode changes can be made via key combinations or the knob. Hot-swap customization: the hot-swap PCB accepts most 3-pin/5-pin switches so you can swap linear or tactile switches without any soldering to tailor feel and sound. Tuned acoustics and improved rebound: a three-layer damping system—EVA foam, IXPE switch pad and sponge case foam—together with silencer foam under the spacebar reduces vibration and enhances key return for a smoother, creamier typing profile. Lighting, macros and durable keycaps: comes with PBT keycaps and full driver support, offering 19 RGB modes, nine color presets, music-sync and macro programming plus GIF uploads for the OLED to personalize both lighting and functionality.
